To facilitate the development of spoken dialog systems and speech enabled
applications, we introduce SGStudio (Semantic Grammar Studio), a grammar
authoring tool that enables regular software developers with little
speech/linguistic background to rapidly create quality semantic grammars for
automatic speech recognition (ASR) and spoken language understanding (SLU). We
focus on the underlying technology of SGStudio, including knowledge assisted
example-based grammar learning, grammar controls and configurable grammar
structures. While the focus of SGStudio is to increase productivity, experimental
results show that it also improves the quality of the grammars being
developed.
